Periodic Reporting for period 1 - VARGAH (Investigating the emergence of mobile and sedentary pastoralism in Neolithic Iran through ancient food residues analyses and radiocarbon dating)

Période du rapport: 2021-06-01 au 2023-05-31

Résumé du contexte et des objectifs généraux du projet

The Vargah project seeks to understand the development of agropastoralism in South West Asia, and in particular the Iranian Plateau, a center for the domestication of sheep and goat ten thousand years ago. The Zagros mountains are a natural habitat for caprines that favoured their domestication from the Neolithic period. Pastoralism development revolutionised human food procurement up to the present day with the reliance on domesticated animals for their meat and milk products.

The objectives are to understand better the subsistence economies of ancient pastoral populations and when they started exploiting the secondary products, particularly the milk of their domesticated goats. Contextualisation of the social organisation of sedentary and mobile groups of pastoralists in a secure timeframe and chronology is also important for the understanding of everyday life and of related aspects of animal management and husbandry practices.

Travail effectué depuis le début du projet jusqu’à la fin de la période considérée dans le rapport et principaux résultats atteints jusqu’à présent

For the Vargah project, hundreds of archaeological pottery vessels were analysed for their lipid residues of dozen human dental calculus for their protein preservation in order to identify ancient food residues and reconstruct ancient diets.

At all the sites we analysed, both the meat and milk originating from domesticated animals (mainly carpines) have been identified. A freshwater aquatic contribution is also suspected at half of the sites and further work needs to be performed to confirm this hypothesis. The results obtained show that dairy exploitation is as least as old as the 7th millennium BC and dental calculus analysis suggest this could be even earlier. Dairy originating likely from sheep/goats was exploited by both mobile and sedentary groups of pastoralists.

Radiocarbon dating of lipids preserved in archaeological pottery vessels allows precision of the chronologies of the sites and provides direct radiocarbon measurement on milk exploitation in the region, thus verifying their antiquity, especially for pottery from disturbed contexts. These results are currently being compiled for publication in a very high-rank journal and they have been presented on several occasions at international conferences in the field of archaeology.

Scientific mediation was also regularly performed to exchange directly with the general public regarding the objectives of the project and method used, or via scientific social media such as blogs (forthcoming online publication, on Bioarchéologie Blog ( https://sstinrap.hypotheses.org/4845 ), the website of the research group (https://archeozoo-archeobota.mnhn.fr/fr) and Twitter (@EmmCasa and @ArchZooBota).

Progrès au-delà de l’état des connaissances et impact potentiel prévu (y compris l’impact socio-économique et les conséquences sociétales plus larges du projet jusqu’à présent)

The project allowed to start documenting and understanding the development of agro-pastoral communities in Iran and South West Asia especially related to the early exploitation of dairy products from caprine. Results obtained to date, show a similar dynamic to the domestication of cattle in Anatolia and Europe, while focussing on diverse animals. The project allowed us to better understand the origins of pastoralism that have impacted the modern food industry.
